I still see it as two different art styles for some reason it's probably how Riley has green eyes and Lucy has black and how she's skinny and how Riley is more medium, I am not saying anything mean just saying in how it looks to me to be two different art styles
Yeah, I like the contrast! I admit Lucy is probably my cartooniest looking character design - I designed them all years ago without necessarily wondering how they all fit together, but I got used to it, haha.
